Reporting a change in income to Benefits Unit: How to ensure that more people comply with their…
'Returning to employment? Don't forget about your benefits!' When individuals receiving benefits return to employment having been registered as unemployed, it is important that they report the change in their income to the Benefits Unit on time, to avoid repayment demands. Why do individuals not comply with this notification requirement? And what interventions could improve compliance? A revised letter from the UWV Employee Insurance Agency and an additional page on the Benefits Unit website…
It’s the end of April in Poland. While everyone
is happy the harsh winter weather is finally getting
milder, the Polish Tax Authority is worried because
62% of the country failed to pay their taxes on time.
Over the past decade, the use of behavioral principles
by tax administrations in different countries has been
gaining ground. Given the country’s tax compliance
rate, Polish authorities and the World Bank tested the
use of behaviorally informed letters to late taxpayers
in order to…
When firms in the UK do not follow the Financial Conduct Authority’s (FCA) Rules or Principles, and consumers incur financial losses as a result, the FCA seeks to ensure customers receive adequate compensation, or redress. In 2011/12, the FCA helped obtain over £150 million worth of redress for consumers. Instances where consumers are due redress do not often receive publicity. Instead, the firm alerts customers to a potential issue, usually in the form of a letter that gives customers…

Encouraging the wearing of face masks in hospitality venues: how to ensure guests wear face masks in…
Due to the COVID-19 pandemic, guests were required to wear face masks on entering and while moving inside hospitality venues. To promote this behaviour, self-persuasion and salience techniques were used in this experiment - with notable success. Following the announced relaxation of face mask requirements, there was a decrease in face mask usage, although this was significantly less in hospitality venues that saw interventions than in venues that did not experience interventions.
Why this…
Telephone surveys were prefaced by a brief message reminding businesses that they had previously committed to participate.

Text messaging to spur vaccination take-up: which type of communication is most effective?
In early 2022, various kinds of text messages were sent to over 100,000 residents of Brabant-Zuidoost who had not yet received a booster jab from the GGD. The results show that the most effective variant − in the 6 days after receiving the text message − led to a 3.2% increase in the number of vaccinations administered. This was the text message saying 'Jouw boosterprik ligt voor je klaar' (You can now book your booster vaccination) plus a randomly allocated date, time and location.

Effective position of call-to-action: Is the response rate higher if the call-to-action appears the…
How can response rates to questionnaires be increased? In the first quarter of 2023, some of the participants in a CBS survey received a letter in which the call-to-action appeared as far as possible at the top of the letter. The other participants received standard letters. The analyses showed that the standard letters produced a significantly higher response rate than the letters in which the call-to-action was placed at the top.
Why this experiment was conducted: high response rate is…
